Description
Captive clutch failure in the Ford 2011-2019's 6R140 is a chronic problem that is difficult to address with stock components or traditional methods. Unlike most lockup converters, the 6R140 clutch does not engage the front cover, it moves away from the engine block and engages a stamped, steel backing plate, which is relatively thin and prone to flexing once you surpass factory power levels. SunCoast addresses the issue by using a custom rigid backing plate that reduces deflection, improving apply conformity. This process provides a more durable reaction surface than OE, improving longevity and reliability for years to come. Another weak point is the OE clutch, which is held together by a set of small, weak leaf springs. These springs are often broken or on the verge of breaking, causing the OE steel clutch plates to break loose and gouge the cover splines. Clutch failure occurs when damage and debris become severe, a particularly frequent issue in heavy-duty trucks that put massive stress on converter components. SunCoast's Category 1 torque converter is built with heat management in mind, and proper clutch engagement, thus is a perfect replacement for customers who do a lot of heavy towing or work out of their vehicles and put reliability as a priority.
